What Are Bare Fibers?

Bare fibers are unmodified, forward-emission laser delivery fibers used across a broad range of medical applications.

They consist of a silica core, cladding, and protective jacket, providing flexible and reliable laser transmission for surgical, diagnostic, and therapeutic procedures.

Lumin Fiber’s bare fibers are available in multiple core diameters (200–1000 µm), compatible with 810 nm – 2940 nm laser systems, and can be supplied sterile for single-use applications.
